[LED] Even though it seems to be of a design that may fail, I have used it non-stop for two years of Production Sound for double system film sound recording and it has worked perfectly. I actually bought two of them in case one failed, but so far I have only used one. It is much better than the one made by Sound Devices, because it has a lower profile when fitted with an XL-B3 battery pack. A professional will pay attention to what they are doing when inserting and removing this, and will never have problems!

[1] I use this with a MixPre-3 and a hirose-to-d-tap cable.  Works as expected.  Its awesome to be able to power the MixPre off camera battery.  Would buy again.


Only suggestion I have is that if you do use this to power your MixPre, and if you feed a signal back into your camera (i.e. not just record to the MixPre, but also send a scratch track signal from the MixPre to the camera), then you will want to get a ground loop isolator to put in your signal chain.  Otherwise the in-camera scratch track will have interference noise.  (The internal MixPre recording remains pristine.)

[1] Honestly I just got it and I'm positively shocked at what a great idea this type of rigging is and how well it seeems to take weight. I've got Hytron batteries on it which are INCREDIBLY heavy and while I wouldn't recommend doing it too much just knowing it can take it in a pinch is great. Great build quality. A idea, A execution

[V-Mount] Great way to add power ports to your build without taking up space on your cage.

[1] I was looking for a small, low profile power system to power my Sony A7Sii, monitor, follow focus and wireless transmitter. I bought this with the Hawk-Woods 98Wh and 150Wh Mini V-Mount batteries. Since the plate comes with 4 built in D-Tap receptacles I am able to have one small but powerful battery source for everything. The plate also takes my full size V-Mount batteries should I need them in.

[LED] This should be the standard battery sled for the Mixpre ii. I don't know what Sound Device is thinking when they design the AA battery sled. Huge design failure!. Keep falling and never securely locks.

I like this sled better (Sound Device has one too). And when using it with Sony NP-F7XX, it last up 8+ hours (4 times longer than AA battery), and I'm sure it will last up to 12 hour (6 times longer) when using Sony NP-F9XX.

The only cons is it's super thight. Don't use it if you plan to remove the sled very often. I suggest use USB-C port for file transfer when using this.

[V-Mount] Adds record start/stop functionality in addition to lens power in conjunction with XDCA-FS7 camera adapter.

[V-Mount] Using this with the Atomos Shinobi 7 and 3 different Gold mount batteries. Build quality is great and the batteries latch in nicely. Just plug in the cable before sliding the receiver plate onto the back of the monitor.

The 3 batteries I am using with this - Indi Pro Tools Micro-Series 98W,
Core SWX Hypercore NEO Slim 98Wh, and an official Anton Bauer Digital Series 90 Gold Mount Battery 87Wh.

[1] This adapter could be sold by dozens if it was better marketed. It is a fantastic idea for anyone with on set monitors (focus pullers, camera ops, video village) . Worth EVERY penny. Hot swap is the bomb.
